First, the power tool briefAs the name implies, electric tools are the general term for the movement of tools driven by electric motors.
Second, the type of power toolsAccording to the classification of the motor, it is divided into three types:
- Brushed motor: The most common power tool motor, with two carbon brush parts, must be replaced with time.
- Brushless motor: Same as the brush motor, except that there are two carbon brushes missing, eliminating the need to replace the carbon brush and toner, but the price is slightly higher than the brush motor.
- Servo motor: It is usually used on high-grade tools. The servo motor can be used to set the rotation angle and rotation speed. It can further detect the drive-sensing device. It belongs to the future generation of new products. The threshold is higher.
